Sony fe 16 25mm f 2 8 g vs sigma 16 28mm f 2 8 dg dn contemporary?

Both are f/2.8 wide zooms with autofocus and no stabilisation, so the choice comes down to reach and mount. The Sony FE 16-25mm f/2.8 G stops at 25mm, which gives you a little more wide-angle character at the long end but less reach. The Sigma 16-28mm f/2.8 DG DN Contemporary goes three millimetres further, and that extra reach is useful for general walk-around shooting. It's also made for both Sony E and L-Mount, so it's the better pick if you might switch systems.

If you shoot Sony E and want the Sony name, the FE is a sound choice. For most people, though, I'd take the Sigma for the extra focal length and the wider mount support. For landscapes, either lens works well, since you'll mostly shoot around f/8 anyway. See the landscape lens guide for why.
